For those who do not know, bill C-22 is the Canadian government's attempt to force encryption backdoors and mandatory metadata retention on all online services in Canada.

If you know anyone who uses WhatsApp, Signal, iMessage, and other encrypted apps, those apps will be blocking Canadians. The blocking will either happen imminently, or suddenly at point in the future without warning (because organizations are not allowed to publicly reveal that they have been told to weaken encryption or illegally retain metadata).
